X and y always equal 1 before u actually know what to actually substitute in for the letters. so if u dont kno then its just 1.
A. f(x^2+5x)=1/x(x+5)
B. Domain:
(−∞,−5)∪(−5,0)∪(0,∞),{x|x≠0,−5}
Range: (−∞,−4/25]∪(0,∞),{y∣y≤−4/25,y>0}
The explanation is hard like the question lol
Range of values of x is .
<u>Step-by-step explanation:</u>
With Rule of concurrency of two triangles, we have,
⇒
⇒
⇒
⇒
⇒
On simplifications,
∴Range of values of x is .
9. To draw the rise, you can follow these steps:
- Identify a point on the line. In this case, this can be:
- Draw a vertical line that rises from that point. See the picture below:
10. To draw the line that represents the run, you need to Draw a horizontal line that goes from the endpoint of the line that represents the rise and extend it until it touches the function. See the picture below:
Therefore, the answers are (See the picture):
